2020-09-15efi: efibc: check for efivars write capabilityArd Biesheuvel
Branden reports that commit f88814cc2578c1 ("efi/efivars: Expose RT service availability via efivars abstraction") regresses UEFI platforms that implement GetVariable but not SetVariable when booting kernels that have EFIBC (bootloader control) enabled. The reason is that EFIBC is a user of the efivars abstraction, which was updated to permit users that rely only on the read capability, but not on the write capability. EFIBC is in the latter category, so it has to check explicitly whether efivars supports writes.

2020-09-15EDAC/ghes: Check whether the driver is on the safe list correctlyBorislav Petkov
With CONFIG_DEBUG_TEST_DRIVER_REMOVE=y, a system would try to probe, unregister and probe again a driver. When ghes_edac is attempted to be loaded on a system which is not on the safe platforms list, ghes_edac_register() would return early. The unregister counterpart ghes_edac_unregister() would still attempt to unregister and exit early at the refcount test, leading to the refcount underflow below. In order to not do *anything* on the unregister path too, reuse the force_load parameter and check it on that path too, before fumbling with the refcount. ghes_edac: ghes_edac_register: entry ghes_edac: ghes_edac_register: return -ENODEV ------------[ cut here ]------------ refcount_t: underflow; use-after-free.

Commit b972fdba8665 ("EDAC/ghes: Fix NULL pointer dereference in ghes_edac_register()") didn't clear all the information from the scanned system and, more specifically, left ghes_hw.num_dimms to its previous value. On a second load (CONFIG_DEBUG_TEST_DRIVER_REMOVE=y), the driver would use the leftover num_dimms value which is not 0 and thus the 0 check in enumerate_dimms() will get bypassed and it would go directly to the pointer deref: d = &hw->dimms[hw->num_dimms]; which is, of course, NULL: #PF: supervisor write access in kernel mode #PF: error_code(0x0002) - not-present page PGD 0 P4D 0 Oops: 0002 [#1] PREEMPT SMP CPU: 7 PID: 1 Comm: swapper/0 Not tainted 5.9.0-rc4+ #7 Hardware name: GIGABYTE MZ01-CE1-00/MZ01-CE1-00, BIOS F02 08/29/2018 RIP: 0010:enumerate_dimms.cold+0x7b/0x375 Reset the whole ghes_hw on driver unregister so that no stale values are used on a second system scan.

2020-09-14vgacon: remove software scrollback supportLinus Torvalds
Yunhai Zhang recently fixed a VGA software scrollback bug in commit ebfdfeeae8c0 ("vgacon: Fix for missing check in scrollback handling"), but that then made people look more closely at some of this code, and there were more problems on the vgacon side, but also the fbcon software scrollback. We don't really have anybody who maintains this code - probably because nobody actually _uses_ it any more. Sure, people still use both VGA and the framebuffer consoles, but they are no longer the main user interfaces to the kernel, and haven't been for decades, so these kinds of extra features end up bitrotting and not really being used. So rather than try to maintain a likely unused set of code, I'll just aggressively remove it, and see if anybody even notices. Maybe there are people who haven't jumped on the whole GUI badnwagon yet, and think it's just a fad. And maybe those people use the scrollback code. If that turns out to be the case, we can resurrect this again, once we've found the sucker^Wmaintainer for it who actually uses it.

2020-09-14Revert "mtd: spi-nor: Disable the flash quad mode in spi_nor_restore()"Yicong Yang
Previous patch intends to restore the flash's QE bit when removed/shutdown, but may have some problems and break the flash: - for those originally in Quad mode, this patch will clear the QE bit when unloaded the flash, which is incorrect. - even with above problem solved, it may still break the flash as some flash's QE bit is non-volatile and lots of set/reset will wear out the bit. - the restore method cannot be proved to be valid as if a hard reset or accident crash happened, the spi_nor_restore() won't be performed the the QE bit will not be restored as we expected to. So let's revert it to fix this. The discussion can be found at [1]. This reverts commit cc59e6bb6cd69d3347c06ccce088c5c6052e041e.

On non-EFI systems, it wasn't possible to test the platform firmware loader because it will have never set "checked_fw" during __init. Instead, allow the test code to override this check. Additionally split the declarations into a private symbol namespace so there is greater enforcement of the symbol visibility.

2020-09-10clk: versatile: Add of_node_put() before return statementSumera Priyadarsini
Every iteration of for_each_available_child_of_node() decrements the reference count of the previous node, however when control is transferred from the middle of the loop, as in the case of a return or break or goto, there is no decrement thus ultimately resulting in a memory leak.

2020-09-09IB/isert: Fix unaligned immediate-data handlingSagi Grimberg
Currently we allocate rx buffers in a single contiguous buffers for headers (iser and iscsi) and data trailer. This means that most likely the data starting offset is aligned to 76 bytes (size of both headers). This worked fine for years, but at some point this broke, resulting in data corruptions in isert when a command comes with immediate data and the underlying backend device assumes 512 bytes buffer alignment. We assume a hard-requirement for all direct I/O buffers to be 512 bytes aligned. To fix this, we should avoid passing unaligned buffers for I/O. Instead, we allocate our recv buffers with some extra space such that we can have the data portion align to 512 byte boundary. This also means that we cannot reference headers or data using structure but rather accessors (as they may move based on alignment). Also, get rid of the wrong __packed annotation from iser_rx_desc as this has only harmful effects (not aligned to anything). This affects the rx descriptors for iscsi login and data plane.
